HEATING DEVICE Application filed April 10,

This invention relates to a new article of manufacture and moreparticularly to a heating device and has for its primary object a designof article that may be inexpen- 5 sively produced and uitlizing a pasteform of fuel.

An object of the invention resides in the combining of a collapsibletube with a combustible paste of therequired consistency 0 for theproduction of a new type of heating device.

Another object of the invention resides in the collapsible feature ofthe tube and the consistency of the combustible paste whereby 5 adesired quantity of the paste may be ejected to automatically form awick of the desired shape and length.

Another object of the invention resides in the automatic formation of awick in the O pressing of a tube which will retain its configurationduring the entire burning operation.

A feature of my invention resides in the design and construction of anew article of manufacture in which a collapsible tube may perform thetriplicate functions, as a container for the combustible paste, as anejector for the paste and as a handle during the use of the heatingdevice.

WVith these and other objects in view the invention will be betterunderstood from the following detailed description taken in connectionwith the accompanying drawing, wherein:

Figure l is a perspective View of the device in use.

Figure 2 is a perspective view from another angle.

Figure 3 is a detailed sectional view through a portion of the device.

Again referring to the drawing illustrating one of the many forms of myinvention the numeral 1 designates a collapsible container illustratedas a collapsible tube 2. This tube is provided with a restricted outlet3 of a shape to form the desired type of wick in a manner hereinafterdescribed. Arranged within the tube is a special type of combustiblepaste 4 as it is absolutely necessary that this paste 4 be of therequired con- 1931. Serial No. 529,140.

sistency so that when pressed through the outlet 3 the same will form aWick 5 of the desired shape and length and retain its configurationduring the entire burning operation. It is also very important that thepaste retain its uniform consistency within the tube and will notseparate out and further will not dry or harden. It will be appreciatedthat if the materials separate, a Wick of the desired shape and lengthcannot be produced and if the material hardens the wick cannot be formedby the pressure of the required amount of material through the outlet 8.I am'aware of the fact that various types of combustible paste have beenproduced before for heating and lighting purposes but the specificcharacteristics of the paste are such as to make the same impracticalfor use as a substitute for my invention. To complete the invention Iprovide a cap 6 for sealing the combustible paste when not in use.

From extensive experiments conducted I have found that a paste havingthe desired characteristics can be accomplished by producing an intimatemixture of an alkaline earth, a combustible material and an inflammablefluid. Specifically stated this can be accomplished by producing anintimate mixture of magnesium stearate and alcohol, the relativeproportions of which determining the consistency of the paste and thecharacteristics of the wick. By mixing approximately one part by weightof magnesium stearate with two parts of alcohol, I can produce theconsistency that will meet the desired result, but I wish it to beunderstood that it is within the scope of my invention to vary theingredients of the mixture to accomplish any desired consistency for theproduction of any desired size or configuration of a Wick. It is alsowithin the scope of my invention to change the ingredients orproportions of the ingredients to vary the illuminating effect of theflame or the heating effect of the flame, thereby enabling the articleto be used solely as a source of intense heat or solely as a source oflight.

Therefore, I do not desire to be limited in protection in any mannerwhatsoever, except as set forth in the following claims.

What I claim is 1. As a new article of manufacture, a heating devicecomprising a collapsible container having an outlet and a combustiblepaste in the container of a consistency to form a wick to be pressedthrough said outlet.

2. As a new article of manufacture, a heating device comprising acollapsible tube having a restricted outlet and a combustible i paste inthe tube adapted upon squeezing of the tube to be forced through saidoutlet and I thereby produce a Wick of a consistency to project beyondthe tube a predetermined distance and retain its formation during theburning operation. 1

V In Witness whereof Ihave hereunto set my hand.

ALBERT A. EPSTEIN.
